JACQUARD MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 751,927, tan February 9, 1904.

Application filed May 6, 1903. Serial No- 155,894. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. KUENNETH, a citizen of the United States, residing in Bronx borough, New York city, in the county and State of New York, have invented new and useful Improvements in Jacquard Mechanism for Looms, of which the following is a specification.

This invention relates to mechanism applicable to double-lift single-cylinder machines and can be practically employed for weaves known as end-and-end or two-face fabrics. By means of this mechanism two leashes or heddles are controlled by one needle.

This invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a side elevation of a loom embodying this invention. Fig. 2 is a section of a knife and loose blade with a regular hook in position to engage or be lifted. Fig. 3 shows a reverse hook in position to be lifted. Figs. t and 5 show castings or brackets to seat or support a loose blade in the grilf. Fig. 6 shows a sectional view of the patterncylinder with needles and hooks. Fig. 7 shows a view like Fig. 6, but with some'of the needles pushed or shifted by the card. Fig. '8 shows the loose blade in the griff or knife. Fig. 9 shows one of the outer rows of hooks. Fig. 10 shows a front view of the patterncylinder and hooks.

In certain existing types of machines as known there is a needle for every leash or heddle. By having two heddles controlled by one needle one-half the needles heretofore required can be dispensed with. In this manner the pattern-card can be reduced one-half, and labor, material, and the design can also be re= duced, as in the case'of two-face fabrics, one end or thread is up while the other thread is down.

In stating, however, that the invention is applicable to a double-lift machine it should be noted that this system is applicable also to a single-lift or rise and fall machine, as will appear from the description of this invention.

In the drawings the letter a indicates the griff mechanism or knives as used on singlecylinder double-lift machines. Attached to such knife is a casting or bracket 6, and a loose blade or knife is shown at 6.

At 0 is shown what may be called a reverse hook and at CZ a regular jacquardhook. A needle is shown at e, a four-eyed needle for controlling two pairs of hooks which lift two leashes in the harness being shown.

The cylinder f is provided for the patterncard g to act in conjunction with the needles guided by the board 72..

It is seen that a needle controls two heddles or leashes. By having a needle control two heddles or hooks c and d the pattern can be reduced, and as these hooks are reverse hooks or face in opposite directions, one of the books 0 or d is always engaged by the griff or knife. If the needle enters a hole in the pattern-card, the hook c is clear and hook d in position to be engaged by the griif. If the needle is moved by the cylinder or a'full part ofthe card, the hook at is in clearing position or free from the griff as the latter moves or rises and the hook c is in position to be engaged or lifted.

Of course in speaking of one hook pair 0 and d with its needle it is understood that the description of one explains the action of all such hooks and needles and that as is the case in looms a series or plurality of pairs of hooks and needles are employed. The blade 5 is dropped or placed loosely in or on the casting Z). Such blade is free to be lifted out or removed, in which case the hooks 0 would be out of use for the time being, but hooks 61 would still be in operation. The machine could then be operated with only one set, (Z, of hooks in action.

The casting b or rather its blade 6 and the blade (1. form an oppositely-facing or bifurcated knife for the reverse hooks d and c.

The hook 0 representing one face of a fabric and hook d the opposite face of such fabric, it is manifest that with both sets of hooks in action a two-face fabric is produced.

In addition to hooks c and (l are shown the outer rows of hooks f, Fig. 10, which are the ordinary hooks now in use on all jacquard mechanism and which are shown retained in this construction and which can serve several purposes. For example, this outside row of hooks f can be used to press back the loose blade 6 to prevent hooks 0 being raised when the hooks d should be raised.

The loose blade I), it may be noted, prevents wear or rubbing of the hooks 0 and the needle against one another, as the swinging blade en ables its hook to remain practically in vertical position when rising and falling through the eye of the needle.

As to other parts of the loom, such as the harness and the mechanism for operating the griif and the pattern-cylinder, no description is deemed necessary, as the levers of actuating mechanism employed can be the same as in all jacquard mechanism.

What I claim as new, and desire to secure by Letters Patent, is-

1. A jacquard mechanism comprisinganeedle, consecutive or adjacent hooks controlled by said needle, and succeeding leashes connected to said hooks, each leash having its trolled by said needle, and adjacent leashes, each hook pair being connected to one leash and I facing knife.

.. free from the other leashes.

3. A jacquard mechanism comprising a needle, two pairs of alternately-acting hooks controlled by such needle, a grifi comprising a fixed blade for one set of hooks and a loose blade made to face in the opposite or reverse direction from the fixed blade for the other "set of hooks.

4. A jacquard mechanism comprising an oppositely-facing or bifurcated knife, and hooks independent or separate from one another and adapted to engage said oppositely- 5. A jacquard mechanism comprising an oppositely-facing or bifurcated knife provided with a fixed and a loose blade.

6. A jacquard mechanism comprising reverse hooks and a knife having a loose removable blade for one set of hooks and a fixed-blade for the other set.

7 A jacquard mechanism comprising a griif with a loose blade or knife adapted to swing to prevent wear of the hook and needle, afixed blade, hooks adapted to be engaged by the fixed blade, and a second set of hooks separate from the first named hooks and adapted to be engaged by the loose blade.

8. A jacquard mechanism comprising a griff mechanism with a loose blade or knife, a four-eyed needle and two pairs of oppositelyfacing hooks adapted to be alternately actuated by the griff mechanism, one pair of said hooks adapted to be engaged by the loose blade.

9. A jacquard mechanism or loom comprising a needle, two alternately-acting heddles or leashes controlled by such needle, a griff comprising a fixed blade for one set ofheddles, and a loose removable blade for the other set of heddles, so that on the removal of said loose blade one set of heddles becomes inactive while leaving the other set to continue in action.

10. A jacquard mechanism or loom comprising a needle, reverse hooks engaged by the needle, a griff or knife for one set of hooks, and a loose blade carried by the knife and made to engage the reverse hooks, said blade being removable and replaceable to bring one set of hooks out of and into action while leaving the other set of hooks to be actuated by its knife.

11. A jacquard mechanism or loomcomprising a needle, hooks engaged by the needle, and a grif'f for the hooks comprising a fast and a loose blade.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE w. KUENNETH.
